Abstract: An overview of the radio observations during October 2025 is given.

 

The graphs show both the daily totals (Figure 1) and the hourly numbers (Figure 2) of “all” reflections counted automatically, and of manually counted “overdense” reflections, overdense reflections longer than 10 seconds and longer than 1 minute, as observed here at Kampenhout (BE) on the frequency of our VVS-beacon (49.99 MHz) during the month of October 2025.

The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:

Local interference and unidentified noise remained very limited and quite weak lightning activity was only registered on the 20th. However, there were fairly strong solar flares almost daily, mostly of type III.

This month, several showers were active, with the Orionids especially standing out with an increase in long-duration reflections which peaked on October 22nd. Also on October 10th, there was a clear surge of overdense reflections between 15h and 18h UT when the Draco radiant was near the local zenith. Further analysis of the registrations shows several other smaller showers.

During this month 17 reflections with a duration of more than 1 minute were observed. A selection of some notable or strong reflections is shown in Figures 3 to 20. Many more are available upon request.

In addition to the usual graphs, you will also find the raw counts (subject to strict reservations as previously said) in cvs-format from which the graphs are derived. The table contains the following columns: day of the month, hour of the day, day + decimals, solar longitude (epoch J2000), counts of “all” reflections, overdense reflections, reflections longer than 10 seconds and reflections longer than 1 minute, the numbers being the observed reflections of the past hour.
